I was under the impression that setting deinterlacing in web admin was all that was required. Is this still the case? I'm seeing lots of lines in mythtv.Barney

You should setup the MythTV deinterlacer settings as far as i know still in 0810. If your using VDPAU then that is one to choose as it has by far the best performance/quality (choose the VDPAU de-interlacer that matches your nVidia hardware of course)

Are you guys talking about the video playback profiles, eg. CPU++, CPU-, Slim, etc? If so, I have found that I cannot use any of the VDPAU related ones as the TV takes about a minute to respond to any actions and/or crashes. Am using a nvidia ION atom 330 effort (VDPAU is set in web admin).

Actually this md just has a keyboard/mouse and a rf emprex windows remote. So probably not the gyration this time.

I've got a dual core revo which is running fine with none of these issues and the gyration 3101. Just got another dual core to replace the single core revo. I'll keep testing and report back if I discover anything.Barney

SOLUTION BELOWOK. The dual core has arrived and is exactly the same. Freezing as soon as F7/F6 etc is pressed. I have experimented with deinterlacing within mythtv frontend. This seems to be the problem.

When deinterlacing is set to none there is no problem at all. As soon as any deinterlacing is set on a vdpau playback profile the freezing happens as described above.

Running top on the md shows mythtvfrontend and OrbiterGL maxed out at over 100% when F7 is pressed. This lasts around a minute before settling down to normal cpu usage but the ui is unusable. A right click to clear the ui also results in a 100% cpu for another minute.

I have to ask, have you already updated the LMCE wiki, Barney? I was just browsing the MythTV page for LMCE looking for a place to slot this information in, and it was already there! (near the bottom) http://wiki.linuxmce.org/index.php/MythTV
